Are you ready for a whole new Xbox experience?

And by “a whole new Xbox experience”, I mean that everything’s a bit more square and a bit more green and in two or three days, you’ll probably have forgotten how it looked before.

The dashboard update is scheduled to go live at any moment now, and to commemorate this otherwise instantly forgettable event, Xbox LIVE overlord Marc Whitten has penned a heartfelt and touching letter to Xbox owners.

“Today, we’re launching a new Xbox 360 experience that connects you with your favorite entertainment and games like never before and makes finding and enjoying entertainment as simple as it should be,” he writes, tears of joy cascading down his cheeks.

“It’s a vision we shared at E3 and I’d like to thank you for all of your valuable feedback along this incredible ride and share a little more about what we have in store this holiday – from Beacons, cloud storage and Facebook sharing, to our latest entertainment offerings.

“We strive to continually innovate and bring meaningful experiences to each and every member of the Xbox LIVE community. Currently, our community is already enjoying 2.1 billion hours of entertainment each month. We imagine this number will only continue to grow as you discover enhanced entertainment on Xbox this holiday that is instantly searchable, easily discoverable and enjoyable in extraordinary new ways.

“We hope you enjoy this new chapter in the evolution of Xbox and continue to push us to write the next.”

Sniff.
